Application lcd June 27, 1900. Serial No. 21,829. (No model.)

To all 107mm/ '7T/ riz/(ty concern.'

lle it known thatl, LEOPOLD BERGER@ citizen ofthe United Astates,residing' at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in Motors, ofwhich the following;` is a specification.

'lhis invention relates to new and useful iinprovenients in foot-motors;and its primary object is to provide a device of this characterespecially adapted for use on sewing-machines and similar machines whichare propelled oy foot-power and whereby the inotion of the foot reducedto the minimum.

To this end the invention consists `in the novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showingl the preferred form ofmy invention, and in which- Figure l is a front elevation thereof. Fig.is a side elevation, Fig. 3 is a plan View of the treadle and itssupports. Fig. 1L is a Yfront elevation of a modified forni of thedevice. Fig'. 5 is a section therethrough, and Fig. (i is a plan view ofthe treadle and its support.

teferrinp; to said ligures by numerals of reference, I l are standardsconnected by a suitable top 2,'from which are suspended. hangers 3,Within which is iournaled a shaft 4I, having a weighted. ivlieci orpulley 6 secured thereto and also provided with a double crank 7, asshown. Itods S extend downward from the top and are secured at theirlower ends to a strip 9, connected at each end by Wires or rods IO withthe adjacent standards l. These rods may be provided with suitabletighteiiling ineanruas the turn-knuckles II. A treadle l2 is journaledupon the strip 9 and is provided with an eye I3 at each side of itsbearing. Within each eye is mounted the end of a rod le, which extendsupward to one of the cranks 7, an shown.

In Figs. 4, 5, and l I have shown a modified form of device in which thestrip I5 is journaled in boxes lo, to which the brace-wires IO arefastened. fluitable collars, as 17, are secured to the strip I5 toprevent lateral movement thereof. arms 18 are secured to and extendoutward from the strip l5,and a treadle 19 is suspended therefrom bymeans of pivoted hangers or brackets 20. One of these arms extends tothe rear of the strip and is secured to the cranks 7 in a manner similarto treadle I2. A strip, as 2l, is connected to the standards l, and atreadle 22 is journaled thereon, as shown, said treadle being pro videdwith a flange23 upon its upper surface, as shown.

rllhe operation of the device disclosed in Figs. l, 2, and 3 will bereadily understood. By bearing,r upon the treadle l2 the two cranks 7will receive power through the rods le, and the weight upon the Wheelwill give a steady movement thereto and overcome all deadcenters.

In the construction shown in the modication the heel of the foot isplaced on treadle 22 and the front of the foot upon treadle 19, therebypermitting' an easy movement of the foot with the utilization of theminimum amount of power.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without dcpartiugo)` from the spiritor sacriiicing the advantages thereof, and I therefore reserve the rightto make such changes as fairly fall within the scope of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. The combination With standards and a top connecting.,r the saine; ofa double crankhinge hung from said top; a strip suspended therefrom;brace-rods connecting'the strip and standards; a pivoted lever upon thestrip; and rods secured to the lever at opposite sides of its pivot andto the cranks.

2. The combination with standards and a top; of a double crank suspendedfrom said top; strips; Wires supporting said strips from the top;brace-wires connectingthe strips and standards; pivoted levers upon thestrips; rods secured to one of the levers at opposite sides of its pivotand to the cranks; and a treadle suspended between and from said levers.

3. The combination with standards and a IOO top; of a double cranksuspended from the top; strips; hanging rods connecting said strips Withthe top; braces Connecting the strips and standards pivoted levers uponthe strips; rods connected to the cranks; and to one of the levers atopposite sides of its pivot; a treadle pivotally supported from said le-Vers; a second strip secured to the standards;

and a treadle mounted upon said strips adjan cent to the treadle of thelevers. 1o

In testimony whereof I affix my signature in presence of two Wit-messes.
